Installing GrapheneOS on a Pixel 8 Pro (husky)

First try: CLI

prerequisites

instructions: https://grapheneos.org/install/cli
using Arch Linux (officially supported by CLI installer method) on a Lenovo W510
updated device: Settings -> System -> Software updates -> System update -> Check for update -> "Your system is up to date"

enable OEM lunlocking

If nothing works, try systematic debugging!

Xvnc is the starting place.

The latest docs are here: https://github.com/TigerVNC/tigervnc/blob/master/unix/vncserver/HOWTO.md

Don't put a xstartup file in ~/.vnc; this is deprecated.

Don't have a Xsession file in /etc/X11; this messes things up.

Create a working OpenVPN configuration on Arch Linux

Most OpenVPN tunnels only support IPv4. Thus, the system has to be configured such that IPv6 is disabled. Moreover, DNS leaks are still possible and thus, the DNS configuration needs to be adjusted as well.

On Arch, install update-systemd-resolved from AUR (GitHub repo). The following lines then go in the OpenVPN configuration:

	#!/bin/bash

	# e.g. $0 xfce4-terminal
	echo "setting terminal to open from Nemo to" $@
	gsettings set org.cinnamon.desktop.default-applications.terminal exec $@

	# (some build stuff already installed for kernel update, I think)

	sudo apt-get install git cmake libopenmpi-dev libnetcdff-dev libscalapack-openmpi-dev libblas-dev liblapack-dev

	git clone https://github.com/ORNL-Fusion/Stellarator-Tools.git

	# into setup_cmake:
	elif [ $MACHINE_ID == "eqrec0" ] \|\| \
	[ $MACHINE_ID == "eqrec1" ]
	then

	# Make Git fetch all remote branches.
	# from https://stackoverflow.com/a/25941875

	git config --get remote.origin.fetch
